Anniversary outfit - Special occasion casual dress!

It has been raining the last couple of days here in LA (finally!), but last week was really nice. I had my anniversary with the boyfriend and we had a casual date night out with dinner and a movie, it was quite nice! Here is what I wore, a really cute, comfy sundress that I bought in Hawaii! I fell in love with the high-lo look of this dress, and how flow-y it is! The color is one of my favorites, and I used black accent pieces that I have blogged about before (the purse, the sandals).
I have been meaning to post about this outfit all week but have been swamped with work!

What do you think of this look? What would you wear to a casual date?
